ABSTRACT

El lupus eritematoso sistémico es una enfermedad autoinmune, de curso crónico con afectación multisistémica. Las manifestaciones oculares del lupus eritematoso sistémico pueden afectar cualquier estructura del ojo. La formación de catarata y la aparición de la diabetes secundaria asociada con el tratamiento esteroideo prolongado es frecuente en estos pacientes. Se presenta el caso de una paciente femenina de 69 años, con antecedentes de lupus eritematoso sistémico de más de 20 años de evolución, tratada con 5 mg diarios de prednisona oral en dosis de mantenimiento. Refiere, además, diabetes mellitus tipo 2 controlada de más de 10 años de evolución. Asiste a la consulta de Oftalmología por disminución de la visión y se diagnostica catarata en el ojo derecho. Se realiza facoemulsificación con implante de lente intraocular plegable, previa profilaxis para la endoftalmitis. La catarata asociada a la diabetes secundaria en los pacientes con lupus eritematoso sistémico justifica el uso de profilaxis antinflamatoria con esteroides tópicos y sistémicos para asegurar una mínima inflamación posoperatoria y mejorar el pronóstico visual(AU)


Systemic lupus erythematosus is a chronic autoimmune disease of multisystemic involvement. Ocular manifestations of systemic lupus erythematosus may present in any structure of the eye. Cataract formation and the appearance of secondary diabetes associated to prolonged steroid therapy are common in these patients. A case is presented of a female 69-year-old patient with a history of systemic lupus erythematosus of more than 20 years' evolution, treated with 5 mg daily of oral prednisone at maintenance doses. The patient also reports controlled diabetes mellitus type 2 of more than ten years' evolution. Her main concern in attending Ophthalmology consultation is vision reduction. Cataract is diagnosed in her right eye. The treatment indicated is phacoemulsification with foldable intraocular lens implantation following prophylaxis for endophthalmitis. Cataract associated to secondary diabetes in patients with systemic lupus erythematosus justifies the use of anti-inflammatory prophylaxis with topical and systemic steroids to ensure minimum postoperative inflammation and improve visual prognosis(AU)

ABSTRACT

Resumo Objetivo: Identificar associação entre qualidade de vida e manifestações clínicas e sintomas de depressão em indivíduos com Lúpus Eritematoso Sistêmico. Métodos: Estudo quantitativo, realizado com 141 indivíduos com lúpus em acompanhamento no ambulatório de reumatologia de um hospital universitário. Os dados foram coletados mediante entrevistas, utilizando o WHOQOL- bref , a Escala Cognitiva de Depressão e o questionário de caracterização sociodemográfica. Para análise, os dados foram digitados em planilha no Microsoft Excel® e analisados no Statistical Analysis Software, utilizando o Odds Ratio para medida de estimativa do risco e ajustes de modelos de regressão logística binária para cada uma das covariáveis de interesse. A significância estatística foi estabelecida quando p<0,05. Resultados: Dos 141 participantes, 135 (95,7%) era do sexo feminino, 81 (57,9%) tinha mais de 40 anos e 89 (63,1%) tinha diagnóstico de lúpus há mais de cinco anos. A presença de algumas manifestações clínicas relacionadas à exacerbação da doença aumenta as chances de uma percepção insatisfatória da qualidade de vida em todos os domínios do WHOQOL- bref , sendo que o maior número de manifestações associadas à percepção insatisfatória da qualidade de vida foi observado no domínio saúde física, seguida pelo domínio saúde psicológica. A presença de sintomas de depressão também apresentou associação com percepção insatisfatória em todos os domínios do WHOQOL- bref Conclusão: As manifestações clínicas que caracterizam a atividade da doença, bem como a presença de complicações aumentam as chances de uma percepção insatisfatória da qualidade de vida e esta, por sua vez, aumenta as chances de o indivíduo apresentar sintomas depressivos.

Abstract Objective: To identify an association between quality of life and clinical manifestations and symptoms of depression in individuals with systemic lupus erythematosus. Methods: This is a quantitative study conducted with 141 individuals with lupus under follow-up at the rheumatology outpatient clinic of a university hospital. Data were collected through interviews using the WHOQOL-bref, the Cognitive Depression Scale and a sociodemographic characterization questionnaire. For analysis, data were entered in a spreadsheet in Microsoft Excel®and analyzed in Statistical Analysis Software, using Odds Ratio to measure risk estimation and adjustments of binary logistic regression models for each of the covariates of interest. Statistical significance was set at p < 0.05. Positive and negative predictive values were calculated for the diagnostic variables that presented statistical significance. Results: Of the 141 participants, 135 (95.7%) were female, 81 (57.9%) were over 40 years old and in 89 (63.1%) lupus had been diagnosed for more than five years. The presence of some clinical manifestations related to exacerbation of the disease increases the chances of an unsatisfactory perceived quality of life in all WHOQOL-bref domains, and the highest number of manifestations associated with unsatisfactory perceived quality of life was observed in the physical health domain, followed by the psychological health domain. The presence of symptoms of depression was also associated with unsatisfactory perception in all WHOQOL-bref domains. Conclusion: The clinical manifestations that characterize the activity of the disease, as well as the presence of complications, increase the chances of an unsatisfactory perceived quality of life and this, in turn, increases the chances of individuals presenting depressive symptoms.

ABSTRACT

Antecedentes: El Lupus Eritematoso Sistémico es una enfermedad autoinmune, sistémica, que involucra diferentes órganos incluyendo el corazón. Una de las manifestaciones cardíacas más comunes es la pericarditis; sin embargo, también se pueden presentar otras formas de afectación cardiaca entre las que se incluye la enfermedad arterial coronaria, arteritis y enfermedad valvular. Una de las presentaciones raras del lupus eritematoso sistémico incluye la miocarditis y una vez sospechada, debe ser diagnosticada y tratada con prontitud para evitar consecuencias fatales para el paciente. Descripción del caso: Presentamos un caso de una paciente femenina de 31 años con historia de dolor torácico, fiebre, fatiga, alteraciones ecocardiográficas y niveles elevados de troponina, a quien se le diagnóstico miocarditis y confirmación de Lupus Eritematoso Sistémico. El manejo fue terapia anti-isquémica e inmunoreguladores, con respuesta terapéutica y evolución satisfactoria. Conclusión: La miocardiopatía clínicamente evidente rara vez es la manifestación inicial de Lupus Eritematoso Sistémico, aunque también puede presentarse en el curso de la enfermedad con disfunción ventricular izquierda, insuficiencia cardiaca aguda y edema pulmonar, es de progresión rápida y requiere de diagnóstico y atención temprana, manejo multidisciplinario para evitar complicaciones fatales...(AU)

ABSTRACT

Resumen: Introducción: Al menos 50% de los pacientes pediátricos portadores de artritis idiopática juvenil (AIJ) continuará control en reumatología adulto. La clasificación de la Liga Internacional de Asociaciones de Reumatología (ILAR) vigente, actualmente en revisión, difiere de la clasificación de las artritis inflamatorias del adulto. Se ha reportado cambios de categoría en 10,8% de los pacientes durante el seguimiento. Objetivo: Analizar los pacientes con AIJ seguidos al menos 7 años para objetivar cambios de diagnós tico en la transición, e identificar factores de mal pronóstico funcional. Pacientes y Método: Estudio retrospectivo en base a registros clínicos. Se incluyó a la totalidad de los pacientes con AIJ controla dos en policlínico pediátrico del Hospital de Puerto Montt entre el año 2005 y 2017, que cumplieron siete o más años de seguimiento. Se realizó análisis descriptivo en base a variables clínicas: categoría diagnóstica, tiempo de evolución al diagnóstico, actividad clínica y serológica, y tiempo de evolución al inicio de la terapia farmacológica. Resultados: Se evaluaron 18 pacientes, 3 Oligo-articular (OA) persistente, 1 OA extendida, 4 Poli-articular (PA) factor reumatoide (FR) negativo, 4 PA FR positivo, 5 Sistémicas, 1 Psoriática, todos con seguimiento mayor a 7 años. Once de 18 niños fueron transfe ridos a adultos. Tres de 11 cambiaron de diagnóstico a Artritis Reumatoide (AR) más otra enferme dad autoinmune: Síndrome de Sjögren + Lupus eritematoso sistémico, Púrpura trombocitopénico inmune, Enfermedad autoinmune no clasificada y cinco de 11 niños de categoría ILAR: OA a Artritis reumatoide juvenil, OA extendida a PA FR negativo, 3 Sistémicas a PA FR negativo. Edad de inicio, formas poli-articulares, retrasos en diagnóstico y comienzo de terapia se asociaron a secuelas e infla mación persistente. Conclusiones: Ocho de once pacientes transferidos cambiaron denominación diagnóstica y/o presentaron otras enfermedades autoinmunes. Algunos factores de mal pronóstico deben mejorar.


Abstract: Introduction: At least 50% of pediatric patients with Juvenile Idiopathic Arthritis (JIA) will require continued fo llow-up in adult rheumatology. The present International League of Associations for Rheumatology (ILAR) classification, currently under revision, differs from its classification of inflammatory arthritis in adults. Category changes have been reported in 10.8% of patients during follow-up. Objective: To analyze JIA patients in follow-up for at least 7 years to detect diagnosis changes during transition to adult care, identifying factors of poor functional prognosis. Patients and Method: Retrospective study based on medical records of JIA patients seen at the pediatric polyclinic of the Puerto Montt Hospital between 2005 and 2017, who were monitored for at least 7 years. Descriptive analysis was performed according to clinical variables: diagnostic category, evolution before diagnosis, clinical and serological activity, and evolution before starting drug therapy. Results: We evaluated 18 pa tients, corresponding to 3 patients with persistent oligoarticular arthritis (OA), 1 with extended OA, 4 with polyarticular arthritis (PA) rheumatoid factor (RF) negative, 4 with PA RF positive, 5 with syste mic JIA, and 1 with psoriatic arthritis, all have had follow-up more than 7 years. 11 out of 18 patients transitioned to adult care. Three out of 11 patients changed diagnosis to Rheumatoid Arthritis (RA) plus another autoimmune disease such as Sjögren's Syndrome + Systemic Lupus Erythematosus, Immune thrombocytopenia, or unclassified autoimmune disease, and 5 out of 11 children changed ILAR category from OA to Juvenile Rheumatoid Arthritis, extended OA to PA RF negative, and 3 from Systemic arthritis to PA RF negative. Age of onset, polyarticular forms, delay in diagnosis, and the start of therapy were associated with sequelae and persistent inflammation. Conclusions: Eight of the eleven JIA patients who transitioned to adult care changed their diagnosis or presented other autoimmune diseases. Some factors of poor prognosis must improve.

ABSTRACT

Introducción: Los biomarcadores son claves en el diagnóstico y pronóstico del lupus eritematoso sistémico en el cual las manifestaciones clínicas son extremadamente complejas y heterogéneas. Objetivo: Determinar el valor clínico de los inmunocomplejos circulantes en pacientes con lupus eritematosos sistémico. Métodos: Se determinaron los niveles séricos de inmunocomplejos fijadores del C1q y de los anticuerpos anti-ácido desoxirribonucleico de doble cadena (anti-ADNdc), anti-nucleosoma (anti-Nuc) y anti-proteínas ribosomales (anti-RibP) por el ensayo inmuno-adsorbente ligado a enzima (ELISA) en 93 pacientes con diagnóstico de lupus eritematosos sistémico. Se utilizaron exámenes no paramétricos para probar la asociación entre los inmunocomplejos y los auto-anticuerpos. La frecuencia de nefritis lupica en los grupos de pacientes positivos y negativos de inmunocomplejos circulantes se comparó mediante Chi cuadrado. Resultados: Los inmunocomplejos se encontraron en 24 (25,8 por ciento) pacientes con lupus eritematosos sistémico. Los pacientes que presentaron los títulos más altos de inmunocomplejos fueron los positivos a los tres auto-anticuerpos usados (p=0,044). Se encontró correlación directa entre los niveles de anti-RibP y los inmunocomplejos (Rho=0,303, p=0,003) y entre los anti-ADNdc y anti-Nuc (Rho=0,449, p=0,001). La nefritis lúpica se presentó en 58,3 por ciento de pacientes con inmunocomplejos, y 31,9 por ciento pacientes negativos de inmunocomplejos (p=0,213). Conclusiones: Los inmunocomplejos circulantes caracterizaron una fracción menor de pacientes con lupus eritematosos sistémico. La presencia de estos no se asoció a los anticuerpos anti-ADNdc ni a la nefritis lupica(AU)


Introduction: Biomarkers are essential in the diagnosis and prognosis of systemic erythematous lupus in which clinical manifestations are extremely complex and heterogeneous. Objective: To determine the clinical value of circulating immunocomplexes in patients with systemic erythematous lupus. Methods: Serum levels of C1q-binding immunocomplexes and anti-double-stranded deoxyribonucleic acid (anti-dsDNA), anti-nucleosome (anti-Nuc) and anti-ribosomal proteins (anti-RibP) were determined by enzyme-linked immunosorbent assay (ELISA) in 93 patients diagnosed with systemic lupus erythematosus. Nonparametric tests were used to test the association between immunocomplexes and auto-antibodies. The frequency of lupus nephritis in the circulating immunocomplex positive and negative patient groups was compared using Chi square. Results: Immunocomplexes were found in 24 (25.8 percent) patients with systemic lupus erythematosus. The patients with the highest immunocomplex titers were positive for the three autoantibodies used (p = 0.044). A direct correlation was found between the levels of anti-RibP and immunocomplexes (Rho = 0.303, p = 0.003) and between anti-dsDNA and anti-Nuc (Rho = 0.449, p = 0.001). Lupus nephritis occurred in 58.3 percent of immunocomplex patients, and 31.9 percent immunocomplex negative patients (p = 0.213). Conclusions: Circulating immunocomplexes characterized a smaller fraction of patients with systemic lupus erythematosus. Their presence was not associated with anti-dsDNA antibodies or lupus nephritis(AU)

ABSTRACT

Introducción: El lupus eritematoso sistémico es el modelo clásico de enfermedad autoinmune. En el desarrollo de la enfermedad intervienen varios tipos de inmunoglobulinas, con predominio de la IgG, IgM e IgA. Objetivo: Describir la utilidad del cociente albúmina/globulina como un indicador de actividad en el lupus eritematoso sistémico. Desarrollo: Se estima que el 50 por ciento de los pacientes con lupus eritematoso sistémico muestran una hipoalbuminemia con una hipergammaglobulinemia. La hipoalbuminemia en mayor medida está relacionada con la presencia de nefritis lúpica. La mitad de los pacientes con nefritis lúpica presentan proteinuria en el orden del síndrome nefrótico. Esta proteinuria iguala o invierte parcialmente el valor del cociente albúmina/globulina. El cociente albúmina/globulina invertido por sí solo es insuficiente para afirmar la presencia de actividad en el lupus eritematoso sistémico. Se deben excluir otras entidades clínicas causantes de hipergammaglobulinemia policlonal. Los criterios de actividad del lupus eritematoso sistémico incrementan la sensibilidad del cociente albúmina/globulina invertido. Conclusiones: La interpretación del cociente albúmina/globulina debe ir aparejada a la estimación de actividad por los criterios clínicos de mayor uso (SLICC, SLEDAI, BILAG). No en todos los pacientes con lupus eritematoso sistémico puede interpretarse como criterio de actividad, por lo que es necesario excluir otras entidades clínicas(AU)


Introduction: Systemic lupus erythematosus is the model of autoimmune disease. Several types of immunoglobulins are involved in the development of the disease, mainly IgG, IgM and IgA. Objective: To describe the potential use of the albumin/globulin ratio as an indicator of activity in systemic lupus erythematosus. Development: fifty percent of patients with systemic lupus erythematosus exhibit hypoalbuminemia with hypergammaglobulinemia. Hypoalbuminemia is mainly related to the presence of lupus nephritis. The half of patients with lupus nephritis develops proteinuria with values of nephrotic syndrome. The proteinuria equals or partially reverses the albumin/globulin ratio. The inverted albumin/globulin ratio is insufficient to establish the presence of lupus activity. Other clinical entities producing polyclonal hypergammaglobulinaemia should be excluded. The systemic lupus erythematosus activity criteria increase the sensitivity of the inverted albumin/globulin ratio. Conclusions: The interpretation of the albumin/globulin ratio requires the activity estimation by different clinical criteria (SLICC, SLEDAI, BILAG). The inverted albumin/globulin ratio cannot be interpreted as a stand-alone indicator of disease activity in every systemic lupus erythematosus patients(AU)

ABSTRACT

Abstract Background Anti-ribosomal P (anti-Rib-P) antibody is a specific serological marker for systemic lupus erythematosus (SLE) and routinely tested by targeting the common epitope of three ribosomal proteins of P0, P1 and P2. This study aimed to investigate if testing antibodies against individual ribosomal protein, but not the common epitope, is required to achieve the best diagnostic benefit in SLE. Methods The study included 82 patients with SLE and 22 healthy donors. Serum antibodies were determined by ELISA and immunoblot. Results The prevalence of each antibody determined by ELISA was 35.4% (anti-Rib-P), 45.1% (anti-Rib-P0), 32.9% (anti-Rib-P1) and 40.2% (anti-Rib-P2) at 99% specificity, respectively. Of 53 patients with negative anti-Rib-P antibody, 21 (39.6%) were positive for anti-Rib-P0, 9 (17.0%) for anti-Rib-P1 and 12 (22.6%) for anti-Rib-P2 antibody. The positive rate of anti-Rib-P antibody detected by ELISA was close to the results by immunoblot (33.4%). Patients with any of these antibodies were featured by higher disease activity and prevalence of skin rashes than those with negative antibodies. Moreover, each antibody was particularly related to some clinical and laboratory disorders. The distribution of subclasses of IgG1-4 was varied with each antibody. Anti-Rib-P0 IgG1 and IgG3 were strongly correlated with disease activity and lower serum complement components 3 and 4. Conclusions Anti-Rib-P antibody is not adequate to predict the existence of antibodies against ribosomal P0, P1 and P2 protein. The examination of antibodies against each ribosomal protein is required to achieve additional diagnostic benefit and to evaluate the association with clinical and serological disorders as well.(AU)

ABSTRACT

OBJECTIVES: Many studies indicate that microRNAs (miRNAs) could be potential biomarkers for various diseases. The purpose of this study was to investigate the clinical value of serum exosomal miRNAs in systemic lupus erythematosus (SLE). METHODS: Serum exosomes were isolated from 38 patients with SLE and 18 healthy controls (HCs). The expression of miR-21, miR-146a and miR-155 within exosomes was examined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Using receiver operating characteristic (ROC) curves, we evaluated the diagnostic value of exosomal miRNAs. RESULTS: Exosomal miR-21 and miR-155 were upregulated (p<0.01), whereas miR-146a expression (p<0.05) was downregulated in patients with SLE, compared to that in HCs. The expression of miR-21 (p<0.01) and miR-155 (p<0.05) was higher in SLE patients with lupus nephritis (LN) than in those without LN (non-LN). The analysis of ROC curves revealed that the expression of miR-21 and miR-155 showed a potential diagnostic value for LN. Furthermore, miR-21 (R=0.44, p<0.05) and miR-155 (R=0.33, p<0.05) were positively correlated with proteinuria. The expression of miR-21 was negatively associated with anti-SSA/Ro antibodies (R=−0.38, p<0.05), and that of miR-146a was negatively associated with anti-dsDNA antibodies (R=−0.39, p<0.05). CONCLUSIONS: These findings suggested that exosomal miR-21 and miR-155 expression levels may serve as potential biomarkers for the diagnosis of SLE and LN.

ABSTRACT

Systemic lupus erythematosus (SLE) is a chronic systematic autoimmune disease. Current methods of diagnosing SLE or evaluating its activity are complex and expensive. Numerous studies have suggested that neutrophil-to-lymphocyte ratio (NLR) is closely correlated with the presence of SLE and its activity, suggesting that it may serve as a diagnostic and monitoring indicator for SLE. Therefore, we performed a meta-analysis to systematically assess the association between NLR and SLE. We performed a literature search until 12 April 2019 in the PubMed, Web of Science, and China National Knowledge Infrastructure databases. Cross-sectional studies comparing the NLR of SLE patients versus those of healthy controls, of active versus inactive SLE patients, and of SLE patients with versus without lupus nephritis were considered for inclusion. Mean intergroup NLR differences were estimated using standardized mean differences and their 95% confidence intervals. Study quality was assessed using the Agency for Healthcare Research and Quality instrument for cross-sectional studies. Fourteen studies with 1,781 SLE patients and 1,330 healthy controls were included in this meta-analysis. The pooled results showed that the NLR was significantly higher in SLE patients than in healthy controls, in active SLE patients than in inactive SLE patients, and in SLE patients with lupus nephritis than in those without lupus nephritis. NLR may be an indicator for monitoring disease activity and reflecting renal involvement in SLE patients. Nevertheless, more high-quality studies are warranted to further validate our findings.

ABSTRACT

In lupus enteritis, circulating pathological immune complexes and thrombosis of intestinal vessels may occur, resulting in acute abdominal pain. We report a 24-year-old woman without a history of systemic lupus erythematosus (SLE), admitted for abdominal pain. An exploratory laparotomy found an appendicitis along with ascites. An appendectomy was performed, and the patient was discharged from the hospital two days later. Three days after discharge, the patient was admitted to another hospital due to the persistence of abdominal pain. An abdominal computed tomography scan showed diffuse mesenteric congestion, concentric bowel loops (double halo or target sign) and the presence of free fluid in the peritoneal cavity. Suspecting a rheumatic disorder, the diagnosis of SLE was confirmed by immunological studies. The patient was treated with pulses of methylprednisolone with good results.

ABSTRACT

Skin involvement in systemic lupus erythematosus (SLE) occurs in more than 75% of patients with this condition. Vesicles and blisters in lupus erythematosus (LE) may be present in SLE secondary to interface vacuolar changes in the epidermis, in discoid LE also secondary to vacuolar epidermal changes, and in bullous LE secondary to antibodies anti-collagen VII deposits with neutrophilic aggregates. In addition, blisters can occur due to the association of SLE with other autoimmune blistering diseases (e.g. bullous pemphigoid). BSLE is a rare blistering disease that mainly occurs in females (30­40 years old), and less frequently in children and adolescents. The most common presentation is rapid and widespread development of tense vesicles and bullae over erythematous macules or plaques. Preferential sites are: superior trunk, proximal superior limbs, and face (lips) with symmetrical distribution. Mucosal involvement is common on perioral, pharyngeal, laryngeal, and genital areas. The involvement of sun-exposed areas is not mandatory. The lesions usually progress with no scarring, but hypo or hyperchromia may be present. We report an 18-year-old female patient with blistering lesions at admission, who was diagnosed with BSLE. She was initially treated with systemic prednisone and hydroxychloroquine. Her condition evolved with relapsing lesions, which required the introduction of Dapsone.

ABSTRACT

Castleman's disease (CD) or angiofollicular lymph node hyperplasia includes a heterogeneous mix of reactive lymphoproliferative processes with well-defined histological features. However, they differ in their localization patterns, clinical expression and etiopathogenesis. There are 4 types, one of them is the multicentric CD that is not associated with any viruses and has re-cently been called idiopathic MCD (iMCD). iMCD is a lymphoproliferative disorder with specific histopathological characteristics, more than one region of affected lymph nodes and absence of infection associated to human herpesvirus 8 and human immunodeficiency virus (HIV). iMCD covers multiple differential diagnoses and might simulate autoimmune diseases such as syste-mic lupus erythematosus. The aim of this article is to report the case of a patient with Castle-man's disease and lupus-like presentation. We present the case of a 38-year-old man without morbid history, who presented lumbago, fever, diaphoresis and asthenia with two months of evolution, associated to bilateral cervical adenopathies. General examinations result negative, antinuclear antibodies at a dilution of 1/640 were positive, and extractable nuclear antigens were positive suggesting moderate Systemic Lupus Erythematosus (SLE) plus secondary Sjö-gren's. Methylprednisolone and Hydroxycloroquine boli were thus initiated. The patient evolved with anasarca, severe anemia, acidosis, polyserositis and multiple mediastinal adenopathies. Immunoglobulin and cyclophosphamide were thus initiated. He later presented fever, throm-bocytopenia and nephrotic syndrome. Biopsy of cervical lymph node reported lymphadenitis with polyclonal plasmacytosis and concentric lymphoid hyperplasia, in agreement with iMCD. Treatment with Rituximab was initiated, which led to the favorable evolution of the patient. iMCD is a systemic inflammatory disease, its presentation corresponds to a constitutional syndrome resulting in a wide differential diagnosis. Every time suspicious adenopathies appear, they must be biopsied since this might lead to a definitive diagnosis

ABSTRACT

Abstract Visceral leishmaniasis (VL), or kala-azar, a serious disease resulting from a systemic infection caused by a protozoan of the genus Leishmania, is potentially fatal to humans. According to data from Sistema de Informação de Agravos de Notificação (Brazil's Information System for Notifiable Diseases) from 2015 to 2016, 6,489 new cases were recorded in Brazil in 22 of the 27 federative units. In addition to typical clinical findings, VL may be associated with autoimmune phenomena, including simulating systemic lupus erythematosus (SLE). We present the first case of autochthonous VL mimicking SLE in Santa Catarina in southern Brazil.

ABSTRACT

El Lupus Eritematoso Sistémico (LES) es una enfermedad sistémica de etiología desconocida y con formas clínicas potencialmente mortales; puede generar disfunción de órganos vitales como riñón, pulmón o sistema nervioso. Se realizó una investigación de tipo descriptiva, transversal, cuyo objetivo fue caracterizar clínicamente a los pacientes con diagnóstico de LES ingresados en el Hospital Pediátrico Dr. Agustín Zubillaga durante el período 2009-2017. La muestra estuvo conformada por 19 casos, predominando escolares (42.1%) seguido por preescolares (31,6%). El promedio de edad fue de 10 años, con un rango entre 6 meses y 14 años. 10,6% de los pacientes tenían antecedentes maternos de LES y Artritis Reumatoide, respectivamente. La fiebre y el edema fueron las manifestaciones iniciales más frecuentes seguidas de artralgias y cefaleas. La nefritis lúpica se presentó en 52,53% de los casos seguida de alteraciones cardíacas como miocarditis y estenosis aórtica (15,79%). Anticuerpos antinucleares positivos se observaron en 45,45% de casos e hipocomplementemia en 22,73%. Se concluye que el LES está presente en la población pediátrica de nuestra región y suele presentarse como una enfermedad con manifestaciones sistémicas severas, principalmente renal y miocárdica, requiriendo hospitalización y tratamiento de remisión oportuno(AU)


Systemic Lupus Erythematosus (SLE) is a systemic disease of unknown etiology and with potentially fatal clinical forms; it can generate dysfunction of vital organs such as kidney, lung or nervous system. A cross-sectional descriptive field investigation was carried out to characterize clinically patients diagnosed with SLE admitted to the Hospital Pediátrico Dr. Agustín Zubillaga during the period 2009-2017. The sample included 19 cases, predominantly school children (42.1%) followed by preschoolers (31.6%). The average age was 10 years old, with a range between 6 months and 14 years. 10.6% of patients had a maternal family history of LES and rheumatoid arthritis. Fever and edema were the most frequent initial manifestations followed by arthralgia and headaches. Lupus nephritis occurred in 52.53% of the cases followed by cardiac alterations such as myocarditis and aortic stenosis (15.79%). Positive antinuclear antibodies were present in 45.45% of cases as well as hypocomplementemia in 22.73%. In conclusion, SLE is present in the pediatric population of our region and usually presents as a disease with severe systemic manifestations, mainly renal and myocardial, requiring hospitalization for timely remission treatment(AU)

ABSTRACT

Abstract Objective To evaluate the effects of pregnancy in systemic lupus erythematosus (SLE) patients. Methods The present article is a retrospective cohort study. Datawere collected from medical records of pregnant women with SLE from January 2002 to December 2012 at Universidade Estadual de Campinas, in the city of Campinas, state of São Paulo, Brazil. Systemic lupus erythematosus and disease activity were defined according to the American College of Rheumatology and the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) criteria respectively. The means, standard deviations (SDs), percentages and correlations were performed using the SAS software, version 9.4 (SAS Institute Inc., Cary, NC, US). Results We obtained data from 69 pregnancies in 58 women. During pregnancy, a new flare was observed in 39.2% (n = 27). The manifestations were most common in patients with prior kidney disease, and mainly occurred during the third quarter and the puerperium. Renal activity occurred in 24.6% (n = 17), and serious activity, in 16% (n = 11). Of all deliveries, 75% (n = 48) were by cesarean section. Twomaternal deaths occurred (3%). Preterm birth was themain complication in the newborns. The abortion rate was 8.7%. Severe SLEDAI during pregnancy was associated with prematurity (100%) and perinatal death (54%). Conclusion Thematernal-fetal outcome is worse in SLE when thewomen experience a flare during pregnancy. The best maternal-fetal outcomes occur when the disease is in remission for at least 6 months before the pregnancy.


Resumo Objetivo Avaliar os efeitos da gravidez em pacientes com lúpus eritematoso sistêmico (LES). Métodos Estudo de coorte retrospectivo. Os dados foram coletados de prontuários de mulheres com LES que engravidaram de janeiro de 2002 a dezembro de 2012 na Universidade Estadual de Campinas, São Paulo, Brasil. Lúpus eritematoso sistêmico e atividade da doença foram definidos segundo o American College of Rheumatology e os critérios doÍndice deAtividadedaDoença de Lúpus Eritematoso (SLEDAI, nasigla eminglês), respectivamente. As médias, os desvios-padrão (DP), as porcentagens e as correlações foram realizados utilizando o software SAS, versão 9.4 (SAS Institute Inc., Cary, NC, US). Resultados Obtivemos dados de 69 gestações em58mulheres. Durante a gravidez, a reatividade da doença foi observada em 39.2% (n = 27). As manifestações mais comuns foram em pacientes com doença renal prévia, e ocorreram principalmente no terceiro trimestre e no puerpério. Atividade renal ocorreu em 24,6% (n = 17), e atividade grave, em 16% (n = 11). De todos os partos, 75% (n = 48) foram por cesariana. Dois óbitos maternos ocorreram (3%). A prematuridade foi a principal complicação nos recém-nascidos. A taxa de aborto foi de 8,7%. O índice SLEDAI grave durante a gestação foi associado à prematuridade (100%) e à morte perinatal (54%). Conclusão O resultado materno-fetal é pior no LES quando as mulheres sofrem crise de reativação durante a gravidez. Os melhores desfechos materno-fetais ocorrem quando a doença está em remissão por pelo menos 6 meses anteriores à gestação.
